## The Mathematical Symbol "Element of with Dot Above (⋵)"

The "Element of with Dot Above" Symbol (⋵)

The ⋵ symbol combines the "element of" symbol (∈) with a dot above it. This symbol is not standard in elementary mathematics or classical set theory as of my last training cut-off in September 2021.

## Visual Representation

This symbol visually is the "element of" symbol (∈) with a dot positioned right above it.

## Potential Uses

While the exact usage might vary depending on context, there are a few places it might be found:

• Advanced Set Theory or Mathematical Logic: Some specialized branches of mathematics introduce modified symbols to convey nuanced meanings or specific conditions.
• Domain-specific Notation: It could be used in a specific field or within a particular paper or book to indicate a particular relation or condition related to set membership that is defined within that context.

## Representation in Other Contexts

In LaTeX, there might not be a direct command for ⋵ by default. If you ever need to recreate this symbol in a LaTeX environment, you could potentially overlay a dot above the standard "element of" symbol. The package stackengine or similar might be helpful in this regard.

## Conclusion

Whenever encountering non-standard symbols like ⋵, it's vital to refer to the specific definitions provided in the context where it's being used, such as the relevant mathematical literature or documentation. Symbols can sometimes have unique meanings introduced by authors to aid in their explanations or to denote specific conditions or concepts.

## Codes for the ⋵ Symbol

 The Symbol ⋵ Alt Code Alt 8949 HTML Code ⋵ HTML Entity ⋵ CSS Code \22F5 Hex Code ⋵ Unicode U+22F5

## How To Insert the ⋵ Symbol

(Method 1) Copy and paste the symbol.

The easiest way to get the ⋵ symbol is to copy and paste it into your document.

Bear in mind that this is a UTF-8 encoded character. It must be encoded as UTF-8 at all stages (copying, replacing, editing, pasting), otherwise it will render as random characters or the dreaded �.

(Method 2) Use the "Alt Code."

If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type 8949. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

(Method 3) Use the HTML Decimal Code (for webpages).

HTML TextOutput
<b>My symbol: &#8949;</b>My symbol: ⋵

(Method 4) Use the HTML Entity Code (for webpages).

HTML TextOutput
<b>My symbol: &isindot;</b>My symbol: ⋵

(Method 5) Use the CSS Code (for webpages).

CSS and HTML TextOutput
<style>
span:after {
content: "\22F5";}
</style>
<span>My symbol:</span>
My symbol: ⋵

(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).

HTML TextOutput
<b>My symbol: &#x22F5;</b>My symbol: ⋵
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22F5 to place the ⋵ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"E9"
ctx.fillText(String.fromCodePoint(x), 5, 5);
Output

(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).

The Unicode for ⋵ is U+22F5. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:
TypeOutput
22F5
[Hold down Alt]
[Press x]

(The 22F5 turns into ⋵. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22F5. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22F5"
document.write("My symbol: " + str)
My symbol: ⋵
